City officials are reviewing designs for 50 Liberty Drive, a 14-story complex on the South Boston waterfront. The L-shaped condo tower would be built on parcel D, which sits directly east of the 109-unit Twenty Two Liberty condo tower now under construction.The new building would include 15,000 square feet of civic and retail space, including areas used by the New England Aquarium, Boston Children’s Museum and the Boston Harbor Island Alliance.

The 21-acre Fan Pier project will contain up to 3 million square feet of mixed-use development. The Boston Fan Pier development, a 252,000-square-foot condo tower, is expected to break ground in late summer.
